22. Classification of Research in Engineering Field
Based on Application: 1. Pure (Basic)Research,
2. Applied Research
Pure Research involves developing and/or testing new theories, models, designs and
correlation that may or may not have immediate application but of immense importance
from the point of view of development of knowledge base in fundamental aspects.
Examples:
•New theory annex added to electromagnetic wave theory,
•Development of analytical procedure to solve a highly complex mathematical model,
•Contribution to number theory etc.,
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 22
23. Classification of Research in Engineering Field
Applied Research refers to research carried out to derive a methodology, model, design or
analysis for problems that have immediate application.
In case of applied research, the the immediate application of anticipated solution dictates the
problem for the research.
Examples:
1.Improvising the atomizer performance for application in a combustor,
2.Developing a new efficient and compact instrumentation / model for wireless
communication.
3. Developing a new methodology for a manufacturing process, Inventing new tools of
management,
4. Analysing a process or event in the light of physics to explain the phenomena reported etc.,
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 23
24. Classification of Research in Engineering Field
Based on Methodology:
1. Experimental, 2. Analytical 3. Numerical
Experimental Research is associated with experimental investigation of a process or theme using
appropriate tools.
Examples:
1.Investigation of flow behaviour of a magnetic fluid in a magnetically resonated duct using
appropriate instrumentation,
2. The performance evaluation of an internal combustion engine with different catalytic converters
using required instrumentation,
3. Evolution and testing of a new strategy for product design as applied to specific class of products
using the current trends in the market, etc.,
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 24
25. Classification of Research in Engineering Field
Analytical Research is associated with the developments of models or solution to the
problems using analytical tools.
Examples:
1. Solution to a set of partial differential equations using error functions or any such new
methods.
2. Development of an analytical tool to collect and analyse data during adoption of a new
management strategy.
3. Evolution of new standards and practices for efficient product design procedure.
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 25
26. Classification of Research in Engineering Field
Numerical Research is associated with the solution obtained for a practical problem using
numerical tools. New numerical tools and procedures may be evolved during this process or
the available commercial numerical analysis based software may be used to solve the
problem.
Examples:
1. Numerical investigation of flow of a non-newtonian fluid through a pin-hole orifice using
a commercial software.
2. Development of a numerical tool to predict the fluid flow behaviour in a hypersonic flow
regime.
3. Evolution of a new tool for grading the customer satisfaction using mathematical,
statistical and numerical methods.

27. • Research Methods are broadly classified as
• Exploratory Research Method
• Conclusive Research Method
Research Design Methods
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 27
28. Experimental Research Design:
The main objective of an experiment is to
measure the influence of the independent
variables on a dependant variable while
keeping the other variables constant
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 28
29. Research Design
Exploratory Research Design:
It is a qualitative flexible approach of investigation wherein the
working procedure is defined and explored for various alternate
approaches in research.
This is a simple procedure and loosely structured.
Example:
A rough route map laid down to carry out research towards
addressing the issue. In this procedure, irrespective of
complexities involved, only skeleton of research design is made.
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 29
30. Research Design
Conclusive Research Design:
It is a quantitative definitive approach of investigation
wherein the working procedure is defined and explored
considering all details starting from literature survey
upto drawing conclusions.
Multiple divisions are shown under Conclusive Research
Design.
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 30
31. Exploratory Research
1. Loosely structured
2. Flexible methodology
3. Does not involve testing of hypothesis
4. Outcomes are specific to problem
defined and cannot be generalised
Conclusive Research
1. Well structured and systematic in
Design
2. Has a formal and definitive
methodology that must be followed
and tested
3. Involves testing of hypothesis
4. Outcomes may be generalised since
they have a theoretical and practical
application
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 31
32. Research Design
Descriptive Research Design:
Descriptive research designs are most
comprehensive and provides detail explanation to
the research problems under investigation.
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 32
33. Research Design
Descriptive Research Design:
In this research, the research design is rigid and not flexible and
must focus on the following:
1. Objectives of study (Why and How)
2. Data collection methodology
3. Selecting the sample
4. Collecting the sample
5. Processing and analysing the data
6. Reporting Findings
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 33
34. Example for Descriptive Research Design:
Case 1: Business Research, an example
• Objectives: To find out the usefulness of playing instruments
in a park
• Data Collection Methods: Questionnaire for users,
manufacturers, service providers etc,
• Selecting the sample: Small park, Big park, park in Rich people
living Area etc, Number of sample..
• Collecting the data: personal meeting, e-mail, through others ….
• Processing and Analysing Data: Statistical and probabilistic
approach, Hypothesis …
• Reporting the Findings: Proper conclusion and applying to larger
mass.
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 34
35. Example for Descriptive Research Design:
Case 1: Engineering Research, an example
• Objectives: To find out the better design for a solar collector.
• Data Collection Methods: previous papers on solar collectors,
manufacturer's design plants etc.
• Selecting the sample: A proper size of solar collector is chosen for
investigation
• Collecting the data: Collection of performance parameters of various solar
collectors of same size from different manufacturer, design, material etc.
Experimentation on solar power collection etc
• Processing and Analysing Data: computation of performance parameters
• Reporting the Findings: Proper conclusion and applying to larger or
particular design.
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 35
36. Experimental Research Design:
• In an experiment, a researcher actively manipulates
one or more casual variables and measures their
effects on the dependant variables of interest.
• Other variables not included may affect the outcome,
hence it cannot prove causality.
• Here one can infer on cause-and-effect relationship.
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 36
37. Experimental Research Design:
Example: Business research: usefulness of playing instrument in a
park
• Identified cause variables may be aesthetics of playing
instrument and ergonomic design of instruments. The
Dependent variable may be the happiness in children using
these instruments.
• Other cause variables ignored may be type of paints used on
the instruments, the timings of opening of park etc.,
• Here one can infer on cause-and-effect relationship but may
not be complete
Dr. S.N. Sridhara, KSSEM sridharasn1964@gmail.com 37
38. Experimental Research Design:
Example: Engineering research: Better design of solar collector
plate
• Identified cause variables may be material of plate of solar
collector and slope of plate mounting . The Dependent variable
may be the maximum heat extracted using Solar plate collector
• Other cause variables ignored may be type water used in the
plate collector, the piping material insulation etc.,
• Here one can infer on cause-and-effect relationship but may
not be complete
